砖拱窑洞的采动损害与保护

DAMAGE AND PROTECTION TO BRICK CAVE DWELLINGS FROM MINING ACTIVITY

砖拱窑洞是陕西矿区广大农村的主要住宅形式之一。在澄合矿区有大量砖拱窑洞的村庄压煤,已严重地影响矿区生产的正常进行。试验表明,砖拱窑洞的抗变能力极差,在采动影响下的变形破坏,有其独有的特点。评估了各种试验性的加固措施,在分析砖拱窑洞变形受力的基础上,探讨了砖拱窑洞的采动损害机理;提出了防护砖拱窑洞损害的有效、可行、经济的保护措施。

The brick Cave dwelling is one of the main residence ferms in vast villages at coalmine ateas in Shaanxi Province. The coal resources are covered by villages consisting of a large number of brick cave dwellings, which has seriously affected the normal production in Chenhe coal mine area. The test shows that the resistance of brick cave dwellings to strain is vety low and the strain damages under influence of mining actvity have their ownpeculiar. characteristics. This papel. has estimated every kind of expeimental measures of reinforcement, made an approach to damage mechanism to brick cave dwellings from mining activity based on the analysis of strain force and put forward the effective, feasible and economic measures for preventing the brick Cave dwellings from damage.
